ANSI/TIA/EIA-568-B.1 Commercial Building Telecommunications Cabling Standard General Requirements
HORIZONTAL CABLING
The definition of horizontal cabling is that portion of the cabling system that extends from the work area outlet, through the cabling in the wall/ceiling/floor and then to the patch panel in the telecommunications room. Thesystem also includes the patch cords at the work area outlet, and patch cords in the telecommunications room. When provisioning for the horizontal cabling system the designer should also consider voice, fire/safety, video, HVAC and EMS. A good design should be aimed at minimizing relocations and maintenance of the horizontal system as it is much more costly to do it later. Topology Horizontalcabling will be installed in a star topology, with each work area outlet being connected via the horizontal cable to the horizontal cross connect in the telecommunications room. Each floor should have its own telecommunications closet, sized as per ANSI/TIA/EIA 569. Any devices required such as baluns and impedance matching devices should not be installed in the horizontal system, but rather, kept...
